DEUBLIN Rotary Union 2425-001-177180 – Dual-Flow Rotary Union for Water Applications
The DEUBLIN 2425-001-177180 rotary union belongs to the 2400/2425 CCM Series, engineered for reliable water transfer in industrial rolls, cylinders, and cooling systems.
This dual-flow (Duoflow) rotary union supports both Mono- and Duoflow operation and is designed for in-shaft installation. Its balanced mechanical seals (SiC/SiC) ensure low wear, minimal leakage, and long service life — even in continuous operation at elevated temperatures.
Key Features
-
Dual-flow (Duoflow) design – allows simultaneous supply and return flow through a single unit
-
Rotor-mounted, self-supported configuration for in-shaft installation (fits Ø 59 mm bore)
-
Balanced mechanical seal system for smooth operation and reduced wear
-
Full-flow design – unrestricted media passage and low pressure drop
-
Field-serviceable design for easy maintenance and long-term reliability
-
Brass housing and elbow for durability and corrosion resistance
-
Stainless steel rotor and supply pipe for precision and strength
-
O-ring pilot (Ø 58.67 mm) for secure, leak-tight connection
